Clarify self-management requirements for code suggestions
What does this MR do and why?
The way we say code suggestions is available to all tiers (which, technically is feasible for the free tier in 16.2 and below), is actually not true. This is because we require ultimate and premium tiers in 16.3+ and require customer success managers in 16.2 and below.
This MR attempts to clarify the distinction.
